Procedure for pectus excavatum

Principal Investigator: Michael R. Harrison, M.D.

Challenge

 

Pectus excavatum is one of the most common major congenital anomalies, characterized by a deep depression of the sternum. For more than 50 years, pectus excavatum has been corrected by major surgical reconstruction through the use of either the Nuss or Ravitch procedures. Both of these procedures require major operations and hospitalization for pain management.

The Magnetic Mini-Mover Procedure (3MP) is a novel minimally invasive method of correcting pectus excavatum developed in an effort to make the pectus excavatum operation better for patients and their families. With this method the deformed costal cartilages are gradually reformed by a controlled gradual outward "pull" on the depressed breastbone. This is achieved with an outpatient surgical procedure and without the need for painful implanted chest wall struts. Two magnets, one implanted inside the chest and attached to the sternum and the second one outside the chest wall and attached to an external brace, are used together to create a magnetic force field which applies a controlled sustained pull.
